The heating tube 12 has externally screwth projecting e e: designed to be cozin ectecl with anexheuet goipe.

.The interior of the cesingg it] is provided with 21, plurality of spec-sch Ziixllilhtl' ribs 20 serving as befiies, and on the outside of the tube 12 ise. similar series if "time ribs 21 which are staggered with tehition to the ribs 550. I

The will of the water-plug 22 between the ecmwthreeded portions 23 and 24 is provided with :1 series of openings 25.

A water conducting tube 22 open at its lower end extends from the outer endvof the plugti-ZZ down into the plug past the openings ings and preventing the engine suction from he connected with on ordinarydrawing water'drops or mist into the fuel' mixture, before the water is thoroughly vaporized.

The water plug 22 is screwed into the upper part of the casing 10 and mto the upper part of the tube 12, so that the lower closed end of the plug 22 is received within the tube 12 while the openings 26 communicate with both compartments of the casing 10.

In the practical use and operation ofmy improved attachment the device is mounted on the engine, and the tubes 16 are connected with the exhaust manifolds by means of bolts extended through the flanges 16. The tubes 17 are connected with the intake manifold .by -means of bolts extended through the flanges 17", and the heating tube 12 is connected with the exhaust pipe.

The water plug is connected with a tube communicating with any suitable source of water supply.

It will be understood that any proper means such as a needle valve may be provided for regulating the flow of Water to the water plug 22. Y

The tube \18 is connected with the carbureter or with the tube leading therefrom.

The suction of the engine will draw the fuel mixturefrom the carbureter through casing 10. h

It will be understood that after the engine has run a short time exhaust gases passing from the exhaust manifold through the tubes 16 'aud thence into'and through the heating tubel2 will thoroughly heat the interior-of my device.

The fuel mixture will, Whirl and strike against the baffle ribs 20 and 21 and will be mechanically broken up during its passage toward the ends of the casing 10 and around the ends, of the partitions 15 and thence through the front compartment of the casing 10 to the tubes17 leading to the intake manifold.

A small amount of Water received in the lower part of the Water plug 22' will be subjected to the heat of the exhaust gases in the heating tube 12 and will be vaporized and will pass into both compartments of the casing 10 and willthere mingle with fuel mixture for furnishing moisture thereto.

The advantages of thoroughly breaking up the hydrocarbon fuel mixture, heating it and adding moisture thereto are Well-known and do not require further elaboration here.

By conducting the fuel mixture to the ends of the casing and returning it to the in-- take tubes, the mixture for all the cylinders is made uniform.

The device is so constructed that it is adaptable for use with any carbureter.

It will be noted that my device is of very simple 'and durable construction and that it may be quickly and-easily mounted on or removed from an eng ne. properly arrang ng the tubes andthe flanges thereon,

the device maybe made to fit a variety of types of engines.
